Description

Cool feeling elastic cushion body

This creation is related to the field of elastic cushions, especially a cool elastic cushion body that can be applied to similar products such as pillows, cushions, cushions or mattresses.

In order to strengthen the heat dissipation function of the conventional elastic pad structure, there is a method of attaching multiple layers of composite materials to each other to enhance the heat dissipation effect. For example, the patent of Taiwan Bulletin No. M540590 is attached to one side of the pillow by means of adhesive or gel. Stick the cool-sensing layer on it to form a pillow with a cool-sensing layer. However, this method often has poor adhesion performance, which leads to poor yield and quality of the end product. In order to improve this kind of bonding method, the Taiwanese Publication No. 201628534 in the case of bedding formed with different materials in the mold proposed that the foam and the heterogeneous unit be made in one mold and made of "integrated molding". However, these methods also have their shortcomings. Because the prototype of the foam and the heterogeneous unit with a cool feeling are in a liquid state, it is difficult to control the mutual adhesion performance of the two materials at the same time in the mold to achieve "integral molding". And for the pillow of the general cool feeling layer, the foam is the main part and occupies a lot of volume. The cool feeling layer only needs to be attached to the thin layer. It is technically difficult to form a cool coating layer with extremely thin film thickness and better uniformity. Therefore, the bedding formed by this process method generally has a poor yield, and the cooling sensation layer is still quite obvious compared to the foam, which leads to the formation between the cooling sensation layer and the foam. Discomfort to the height difference.

In view of this, the author gathered many years of rich experience in related industries, and proposed a cool elastic cushion body to effectively improve the yield problems of similar products such as pillows, cushions, cushions or mattresses with cool function today, and Process is missing.

One of the objectives of this creation is to provide a cool-sensing elastomer with simple manufacturing process, stable yield, and integrated with two heterogeneous materials.

In order to achieve the above purpose, this creation discloses a cool feeling elastic cushion body, which includes: a body and a thermally conductive layer, wherein the system is an elastically compressible foam material; and the thermally conductive layer is made of a PU mixture through the fog It is tightly covered or planted by spraying on part of the surface of the body, wherein the thermal conductivity of the thermally conductive layer is higher than that of the body, and the thermally conductive layer is a non-elastically compressible material. Thereby, the cool feeling elastic cushion body can use the thermally conductive layer to effectively dissipate heat after being applied to the human body. And in terms of manufacturing process, it can stably and quickly complete the advantages of close adhesion of the thermally conductive layer and the body, and the efficiency is also greatly improved.

In one embodiment, the foam material can be made of latex or memory foam.

Preferably, further, since the thermally conductive layer of this creation is made by a PU mixture through atomization spraying, the thermally conductive layer is sequentially stacked by a plurality of micro particles during the spraying process.

In addition, in order to reduce the surface stickiness of the thermally conductive layer, in an embodiment, a plurality of lime particles may be included, and the lime particles are partially filled in the gaps of the micro particles or covered with the micro particles. The surface thus achieves a smooth contact feeling.

Further, preferably, the PU blend comprises a polyether-based material and an isocyanate-based material. In order to make the thermally conductive layer visually clear, the PU mixture may include a dye. And the dye can be a base dye.

Preferably, in still another embodiment, the temperature condition of the atomizing and spraying of the PU mixture is at least 80 ° C.

Preferably, in still another embodiment, the thickness of the thermally conductive layer is less than 1 mm; and the system is one of a pillow, a cushion, a cushion, or a mattress.

According to this, the cool feeling elastic cushion body can use the thermally conductive layer to effectively dissipate heat after being applied to the human body, and in terms of the manufacturing process, it can steadily and quickly complete the advantage of the thermally conductive layer and the body closely adhering to each other. At the same time, efficiency has also been greatly improved.

In order for your reviewers to understand the content of this creation clearly, I would like to refer to the following descriptions and drawings.

Please refer to Figures 1 to 4, which are the schematic diagrams of the cool feeling elastic pad body of the preferred embodiment of the creation, the enlarged schematic view of the heat conductive layer part of the cool sense elastic pad body, the schematic diagram of the cool sense elastic pad system, and another preferred embodiment. Schematic of the cool feeling elastic cushion body. This creation discloses a cool-sensing elastic cushion body 1 including a main body 10 and a thermally conductive layer 12. The main body 10 is an elastically compressible foam material. Such as pillows, cushions, cushions or mattresses and similar products. Furthermore, the thermally conductive layer 12 is made of a PU mixture 14 and is further tightly covered or spread on a part of the surface of the body 10 through a spray spraying method. Taking a pillow as an example, only one side is usually used for contacting the human body, so the PU mixture 14 after spraying and atomizing on the side may be used. In order to make the thermally conductive layer 12 have better thermal conductivity, the thermal conductivity of the thermally conductive layer 12 should be higher than that of the body 10, and the material of the thermally conductive layer 12 is non-elastically compressible, and is elastic with the body 10 The characteristics of compression are different.

Further, the foam material of the body 10 can be selected from latex material or memory foam material, and both of them have good cushioning and elasticity effects for similar products such as pillows. Among them, the main material of latex is rubber tree milk. Because the surface of the latex stomata is usually smooth, dust mites are less able to adhere, and at the same time, they are heat-radiating and breathable. The memory foam can memorize the human body curve, so that all parts of the body fit perfectly to give excellent support, and the characteristics of shock absorption and pressure release can reduce the stress.

Furthermore, taking the pillow as an example, since this creative system is to improve the physical performance of the structure, the PU mixture 14 is used to further coat or install it on the part of the body 10 by spraying and spraying. The surface, and the characteristic of atomized spraying is that it is composed of a plurality of micro particles 120 on the microcosmic level. The thermally conductive layer 12 is formed by stacking the micro particles 120 repeatedly through the atomized spray coating system. Effectively improve the surface uniformity of the thermally conductive layer 12. In addition, in order to make the thermally conductive layer 12 have better thermal conductivity or durability, the PU mixture 14 can be different materials for viscosity, tensile strength, shear strength, stability, thermal conductivity, water resistance, etc. mixing. For example, the PU mixture 14 series of this creation may include a polyether-based material and an isocyanate-based material for the above-mentioned purpose.

According to the description, since the thickness of the thermally conductive layer 12 formed by atomizing spraying in this creation is extremely thin, for example, it is usually set to less than 1 mm. Therefore, in order to enhance the visual presentation of the thermally conductive layer 12, it can also be used in the PU mixture 14. Add a dye, for example, with a base dye as an option. In order to make the spraying and atomizing performance better, the temperature condition of the PU dyeing agent 14 for atomizing and spraying is set to at least 80 degrees C or more.

In terms of material characteristics, due to the heat-dissipating material of the heat-conducting layer 12, the material generally has a slight viscosity, and this viscosity phenomenon may cause undesirable performance such as pollution. However, this creation uses the atomization spraying method to form the thermally conductive layer 12 with the micro-particles 120. Therefore, using the structural characteristics, a plurality of lime particles 16 can be further coated on the thermally conductive layer 12, and the lime particles 16 are further A portion is filled in the gaps of the micro particles 120, or directly covered and adhered to the surfaces of the micro particles 120. Since the sizes of the micro particles 120 and the lime particles 16 are extremely small, even if they are closely packed with each other, even after being washed and dried in water, the effect of smooth touch can be maintained. Compared with the conventional pillows with a cool feeling layer, after washing, they usually show poor adhesion characteristics, so the cool elastic pad 1 of this creation obviously has better effects.

In summary, the cool elastic pad system of this creation uses a PU mixture to form a thermally conductive layer that is tightly covered or planted on the surface of the body by atomizing and spraying. According to this, the cool feeling elastic cushion body can use the thermally conductive layer to effectively dissipate heat after being applied to the human body, and in terms of the manufacturing process, it can steadily and quickly complete the advantage of the thermally conductive layer and the body being closely attached to each other. At the same time, efficiency has also been greatly improved.

The above is only a preferred embodiment of this creation, and is not intended to limit the scope of rights of this creation; therefore, changes, modifications, or replacements of elements with the same function made without departing from the equal scope of this creation are still All should be covered by the patent of this creation.
